My old computer serves as a nice power saving home server for Home Assistant, Nextcloud and some other services. Details will be covered another time.

I was cleaning up some Nextcloud directories and found an ugly bug that somehow led to Nextcloud deleting nearly all of the 2 GBs of data. That was the perfect time to go for some restore drill of my multi-level backup concept.

I adopted the “3-2-1” backup strategy a bit and spread my backups to local disks (Synology Diskstation and the Homeserver) and two remote targets: Wasabi and Amazon Cloud Drive. Currently I still enjoy the unlimited storage plan, let’s see how long this will last.

Needless to say that all backups are encrypted, even these in my house.

I backup all data of the Windows PC since this is the main computer. My Mac is configured to backup a selective subset of the data using Arq and a full backup via Time Machine to my Diskstation. The Homeserver is also scheduled to backup important data using duplicity-backup.sh to Wasabi.

The Diskstation is configured to backup itself on a external disk connected via USB and also to backup the important stuff via the AWS S3 Integration to Wasabi.

Today’s post is all about performance testing websites. PhantomJS is doing a great job here.

AngularJS – Perceived Performance: In a traditional page, measuring the page performance is quite easy; a request is made, the server responds with some HTML and the browser renders it. Done. In a Single Page Application, things get trickier.

YSlow for PhantomJS: PhantomJS is a headless WebKit with JavaScript API. YSlow for PhantomJS is a command line script that allows page performance analysis from live URLs, unlike YSlow for Command Line (HAR) where a pre-generated HAR file is needed in order to analyze page performance. – Tags: performancetesting

collectd – The system statistics collection daemon: collectd gathers statistics about the system it is running on and stores this information. Those statistics can then be used to find current performance bottlenecks (i.e. performance analysis) and predict future system load (i.e. capacity planning).

Hyperfox – HTTP and HTTPs Recording: MITM-Proxy for HTTP debugging. Hyperfox is capable of forging SSL certificates on the fly using a root CA certificate and its corresponding key (both provided by the user). If the target machine recognizes the root CA as trusted, then HTTPs traffic can be succesfully intercepted and recorded. – by CyberPunk

sametmax/0bin · GitHub: 0bin allows anybody to host a pastebin while welcoming any type of content to be pasted in it. The idea is that one can (probably…) not be legally entitled to moderate the pastebin content as he/she has no way to decrypt it.
